PRIMING DEVICE.

Specification of Letters Patent.

Patented Uct,

Application filed April 23, 1918. Serial No. 23042251- To (/71 whom itmay concern:

Be it known that we, Josnrn War. Ln Mann-1 and Haney L. \Vlccnmrs,citizens of the United States,-and residents of the city of New York, inthe county of New York and Queens, respectively, and State of New York,have invented certain new and useful Improvements in Primin Devices, olfwhich the following is a specihcation.

The present invention relates to improvements in starting devices forinternal combustion engines, and moreparticularly to that. type ofstarting devices which is intended to be used with engines upon motorvehicles, although it Will be understood that it is applicable toengines used in other connections.

The main object of the present invention is to provide an improveddevice, by the use of which a snllicient amount of gasolenc, to primethe engine, may be introi'luced into the cylinders of the engine,without the necessity of opening the hood of the motor vehicle to turnthe pet-cocks of the various priming cups.

A further object of the invention is to provide a device of thecharacter specified which is conveniently accessible to the driverwithout leaving his seat, the device being of such a character that itmay be operated by simply pulling a handl located in lront of thedrivers seat.

A still further object of the invention is to provide a device of thistype which may be applied easily to existing motor vehicles as well asto new vehicles, and which is relatively inexpensive and adapted forInanut'ao ture on a commercial scale. v

With these and other objects in view, will more fully appear as thenature of the invention is better understood, the same consists in thecombination, arrangement, and construction of parts hereinafterdescribed, pointed out in the appended claims and illustrated in theaccompanying drawings, it

being understood that many changes may be made in the size andproportion of the several parts and details of construction within thescope of the appended claims without departing from the spirit orsacrificing any of the advantages of the invention,

One of the many possible en'ibodiments of the invention is illustratedin the accompanying drawings, in which Figure l is a side elevation of apriming device constructed in accordance with the present invention;Fig. 2 is a longitudinal vertical section taken therethrough; liig. 3 isa top plan view of the same with some of the elements in otherpositions; and Fist". *l a section taken on line lr loi l ig. n.

In the drawings, the numeral lt iiltill a reservoir, adapted to containa suitable lupiid llyt ll'ficill'llilll, such as Q'LISUiOllt, which istilled into the said reservoir through a nipple ll, covered by a cap t2,the latte-i.- being provided with a vent hole 12'; This reservoir isattached in anv suitable manner to the dash-board, when the engine isapplied to a motor vehicle, and is, preferably, disposed below the hoodof the vehicle. I The reservoir is provided with a small :iuel outlet 3,communicating with the cylinder it of a pump, that is shown in thedrawings as being made integral with the said reservoir, although it maybe secured thereto in any suitable manner. The pump cylinder ex tendsthrough an opening 15 in the dash board l t, and is provided with a rearhead 17 and a from head 18. A little distance in rear of the front head15 there is formed in the cylinder a partition 15), exlemling at rightangles to the longitudinal axis of the said cylinder and dividing thesame into a piston chamber 20 and a compartmcl-it 21, the lattercommunicating through the fuel outlet 13 with the reservoir 10. "Thepartition 19 has an opening 22, through which the piston chambereonununicali-s with the compartment 21. In th from head 18 is formed aperl'oralion 23, with which cooperates an inwardly openingspring-pressed check valve 2 t, for a purpose hereinafter to be described.

In the piston chamber is mounted a piston 25 of any suitableconstruction, the said piston being secured to a piston rod 26, thatextends through the rear head 17 and terminates in a handle 27, To thishandle and to the rear head 17 are attached helical springs 28, whichhave a tendency to hold the piston in its forward position, that is tosay at the beginning of its suction stroke.

The compartment 21 is provided with a discharge opening 29. controlledby a cock 30, the outlet of which is connected by a pipe 31, preferably,with the manifold of the internal combustion engine, with which thepriming device is intended to cooperate. To the plug 3'2 oi the cook 30is pivoted at 33 an actuating bar 34. that extends rearwardly inparallel relation to the piston rod through the dash-board'ltl, and ispro vided with an arm 55, the latter being seated in alongitudinal slot36 in the piston rod, 1 arrangement being such that, when the :on i inits forward position 9), i arm 35 abuts against the rear ecge 37 ot' theslot and the cock is in its closed iosition. The slot 36, on the otherhand, :5 of a length. that its front edge 38 comes nto contact with thearm innnediately erore the piston completes its suction thereby shiftingthe said arm as the stroke is being completed and thus urning the plugof the cock communication between the 29 and the pipe 31. ion of thisdevice is as fol "shining that the piston is in its L L position (Fig.2), obvious y the rah eld by its spring in its es the piston is drawn v,the said check valve is unseated,

vvh be drawn into the compartston chamber 20, which air iuei. therein.The cock 3O closed position until the piston coinpleted'its suctionstroke and in 35 comes into Contact with edge 38 of the slot 36 in thepiston I hen, upon completing the suction "1e said oiston rod causes theactuto more with it, thereby giving turn to the cock plug 32 andopencoininunication between the compart- 21 and the pipe 31. As thepiston is it on its suction stroke, the springs 28 y QXPtUEClH It,therefore, upon the completion of the suction stroke of the i on thehandle "2? l it free, the springs l cause the said piston to move in thee direction, that is to upon its suc ieu partially tie ' stroke. As soonas the expelling, started, the check valve 2i closes n and the fuelWithin the e injected into the pipe 31, n left pen until the rear edge01TH; into cimtact with the mating bar ii and shifts the continued move-:to its closing pos (ion,

tion engines, including a 31 the fuel flows into the intake in the pipeit is drawn into the manifold, from which cylinders of the engine.

Although a single operation of the primer should be suflicient underordinary conditions, the operation can bei'epeated as often I as desiredaccording to the requirements. it is to be observed that a measuredquantity of fuel is'fed during each operation to the enginecylinders,the quantity depending upon the size of the pump cylinder.

What We claim is-- 1. A priming device for internal combustion engines,including a cylinder having an inlet opening communicating With a supplyof liquid hydro-carloon and a valve controlled discharge opening, apiston in said cylinder, a piston rod fixed to said piston having alongitudinal slot, an actuating bar pivoted to the valve controllingsaid discharge opening having an arm extending into said slot, wherebysaid valve h ought to its open position near the end of the suctionstroke of said piston in said cylinder and to its closed position at theend oi the stroke of said piston in the opposite direction.

2. A priming device for internal combusreservoir for containing a supplyof liquid hydro-carbon, a cylinder having a piston chamber and acompartment communicating with said chamber and with said reservoir,said coinpartnient being provided with a valve controlled dischargeopening, a piston in said chamber, a piston rod fixed to said pistonhaving a longitudinal slot, an actuating barpivoted to the valvecontrolling said'discharge opening having an arm extending into saidslot, whereby said valve is brought to its open position near the end ofthe suction stroke of said piston in said cylinder and to its closedposition at the end of the stroke of said piston in the oppositedirection.

Signed at New York, in the county of New York, and State of New York,this 18th day oi April, A. D. 1918.
